If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this problem.

Hyundai Azera models equipped with navigation units may suddenly stop playing audio from all speakers. This includes sound from CD players, radio, navigation, satellite radio, and telephone calls. All other features may still function properly.

The passenger airbag system on late model vehicles is designed to properly classify the type of passenger occupying the passenger seat. Possibilities include an adult, child, or child safety seat. These vehicles are being recalled because the passenger seat occupant may not be correctly classified by the airbag system. As a result the passenger airbag could deploy with a force inappropriate for the passenger seat occupant, increasing the risk of personal injury. Dealers will recalibrate the airbag system to correct this concern.
